python - 根据用户输入创建循环，然后将结果保存为 Python 中的 MUD

Question

我正在尝试做两件事:

1. 在 python 中创建一个循环，为用户提供带有 4 个可能选项的提示；输入“1”、“2”、“3”或其他任何内容。如果用户选择 1、2 或 3，则会向他们显示文本。如果用户输入任何其他内容，他们会看到文本，并再次出现提示。重复此操作，直到他们输入 1、2 或 3。

2. 然后我想从用户那里获取该输入以在该循环之外使用并继续玩游戏。

到目前为止我的解决方案:在发布代码之前，我将对其进行描述，我基本上已将所需的所有代码放入一个不带参数的函数的循环中。然后我在 else 语句中调用该函数。

代码的作用:代码正在按照我想要的方式循环，但我不知道如何“打破”循环以根据用户输入的内容继续。我知道它必须是一个返回，但我想我不知道把它放在哪里。

我尝试过的:调用我输入的函数后:

if blackdoor(decision) == "1":

然后从那里继续，但这不起作用。

代码:

def blackdoor():
    print """After having recently died you awake to find yourself standing in an all white room with a black door that seems to go into the sky forever. What do you do?\n1.Touch the door.\n2.Shout at the door.\n3.Stare at the door."""
    decision = raw_input("> ")
    if decision == "1":
        print "You touch the door. It is as cold as ice. You can feel a vibration pulsing from the door through your body.\n"
    elif decision == "2":
        print "You shout 'Hello?! Is anybody there?!' at the door. But nothing responds. Your voice echoes off in the distance.\n"
    elif decision == "3":
        print "You stare at the door intensely. You envision it opening when all of a sudden you get the feeling of something staring back at you.\n"
    else:
        print "You don't follow instructions very well, do you?\n"
        blackdoor()
    return decision

blackdoor()

如何提取决策输入并将其用作保持游戏继续进行的条件？

Answer 1

您正在递归调用 blackdoor()，但没有返回调用结果。您需要return blackdoor()才能将结果返回给调用者。

一个简单的改变就可以做到；

def blackdoor():
print """After having recently died you awake to find yourself standing in an all white room with a black door that seems to go into the sky forever. What do you do?\n1.Touch the door.\n2.Shout at the door.\n3.Stare at the door."""
decision = raw_input("> ")
if decision == "1":
    print "You touch the door. It is as cold as ice. You can feel a vibration pulsing from the door through your body.\n"
elif decision == "2":
    print "You shout 'Hello?! Is anybody there?!' at the door. But nothing responds. Your voice echoes off in the distance.\n"
elif decision == "3":
    print "You stare at the door intensely. You envision it opening when all of a sudden you get the feeling of something staring back at you.\n"
else:
    print "You don't follow instructions very well, do you?\n"
    return blackdoor()
return decision
